There should not be a gallery/install folder within UBB.threads, the default folders would be:
gallery/default/full/
gallery/default/medium/
gallery/default/thumbs/
Each should contain an index.html document.
It's a simple permission check, it looks for ANY folders and ALL files in the UBB.threads path, if it's a folder it checks if it's chmodded 777, if theres a file it wants it 666.
Any additional folders in the gallery/ folder should be numerated with the forum number they belong to, "install" wouldn't be an option.
